Choosing the Right dexos 1 in oil: Grades, Approvals, & Tips
Selecting the correct dexos 1 in oil isn’t just about finding the label; it involves understanding viscosity grades and verifying official approvals. This section serves as your essential dexos 1 in oil guide.
Deciphering Oil Viscosity Grades
Engine oil viscosity is a measure of its resistance to flow. It’s indicated by numbers like “5W-30” or “0W-20.”
- The first number (e.g., “5W”) indicates the oil’s viscosity at low temperatures (“W” for winter). A lower number means the oil flows more easily in cold weather, providing quicker lubrication at startup.
- The second number (e.g., “30”) indicates the oil’s viscosity at operating temperature. A higher number means a thicker oil at engine operating temperature, offering more protection in high-stress conditions.
Always consult your vehicle’s owner’s manual to find the recommended viscosity grade. Using the wrong grade can affect fuel economy, engine wear, and even void your warranty. Most modern GM vehicles will specify 0W-20 or 5W-30 dexos 1 oils.
Verifying Official dexos 1 Approval
Just because an oil bottle says “meets or exceeds GM specifications” doesn’t mean it’s officially dexos 1 certified. To ensure you’re getting genuine protection, look for the official dexos 1 logo on the oil container. This logo confirms that the oil has passed all of GM’s rigorous tests and holds an official license number.
You can also check GM’s official website for a list of licensed dexos 1 products. This simple step is crucial for guaranteeing you’re using a product that truly offers the promised benefits and protection.
